Boron nitride BN ceramic

نيتريد البورون (BN) is a white, low porosity refractory material with physical and mechanical properties similar to Graphite.
However, unlike Graphite, نيتريد البورون has high thermal conductivity and good thermal shock performance. The most common formulation of Boron Nitride contains boric oxide, which can cause Boron Nitride to absorb moisture, resulting in swelling and property degradation.

We generally choose a form known as hexagonal boron nitride (h-BN). Hexagonal BN is a composite of boron and nitrogen that is both heat and chemically resistant. It is the most robust crystalline type of boron nitride, along with graphite. Since it has a composition identical to graphite, although you will even hear it namedwhite graphitesince it is white in colour. What is more, hardness of hexagonal BN is similar to graphite, so it is very easily to machine the parts into required shape, only one small tip,machining work should be process in dry conditions with no cooling liquid. ايضا, visible dust can be created during machining,so wearing mask and goggle is necessary.
